Answer:
x = 12
Step-by-step explanation:
The total of all the angle is 180 degrees so just divide 180 by the total number of x's which is 5+4+3+2+1 = 15
180/15 = 12
If you wanted to know how much each angle is just plug in 12 for x.
So first angle is just X so it is 12 degrees.
Second angle is 2X so 2x12 = 24 degrees.
and so on for all the angles.
15/24 5/x
cross multiply
15x=120
x=8
